报告题目:ligand-engineered perovskites for achieving high-performance and stable solar cells

报 告 人:张鸿博士(香港大学

报告时间:201882日(周四)下午13:30

报告地点:磬苑校区理工楼b318

报告简介:due to their outstanding optoelectronic properties, metal halide perovskites have been intensively studied in recent years. a certificated power conversion efficiency of 23.3% has recently been achieved in perovskite solar cells (pvscs), which enables them as a very promising candidate to be used for next-generation photovoltaics. however, most of the state-of-the-art pvcss reported so far require tedious layer-dependent high-temperature sintering or annealing processes. this will not only increase the fabrication complexity, cost, and energy consumption, but also hinder the use of flexible substrates for roll-to-roll printing. moreover, thermal annealing for extended periods is known to cause perovskite decomposition, which degrades device performance and stability. it is still challenging to fabricate low-temperature processed pvscs, owing to a trade-off between processing temperature and device efficiency. in this talk, i will introduce our recent progress in ligand-engineered perovskites for room-temperature solution processed high-performance and stable pvscs.
